Speed vs Agility
In the pursuit of operational efficiency, companies often gravitate towards purchasing the latest, largest, and most complex machines. These machines offer higher throughput rates, resulting in a lower cost per unit. However, there are challenges associated with such investments. Operation Managers discover at later stages that any production downtime for maintenance can bring the entire production process to a halt, as backup equipment was not considered due to affordability constraints. Additionally, due to the size and expense of these machines, project managers tend to opt for long production runs to justify the initial investment, which leads to excessive inventory levels. Consequently, it becomes evident that relying solely on big and advanced equipment does not necessarily yield a flexible manufacturing process.
The solution lies in investing in multiple smaller machines instead. This approach provides the advantage of having equipment available to meet immediate production needs while other similar machines undergo repairs. Furthermore, the reduced complexity of lower-capacity machines allows for easy reconfiguration to accommodate different types of production. This versatility enables shorter production runs that align more closely with demand, thus minimizing excess inventory. Additionally, these less complex machines are easier to maintain and require less specialized maintenance technicians, reducing operational costs further.

Nevertheless, there are instances where the use of high-capacity machines remains beneficial. For example, when a company engages in enormously long production runs and faces intense competition, reducing the cost per unit becomes paramount. In practical terms, a company will encounter varying levels of demand for its product mix, necessitating the acquisition of a range of equipment, from low- to high-volume, to effectively match that demand.
By considering a balanced approach that incorporates both high-capacity and low-capacity machines, companies can optimize their manufacturing processes to meet diverse production requirements efficiently. This strategic investment decision, aligned with the demand profile and cost objectives, allows for enhanced operational flexibility, reduced inventory costs, and improved responsiveness to customer needs.
